📊 Excel to CSV Converter
Paste rows copied from Excel and get clean CSV output instantly. Free browser-based Excel (TSV) to CSV converter — no upload, works offline.
Need to turn spreadsheet data into a CSV file that other tools can actually read? Our Excel to CSV Converter does exactly that, with zero uploads. You copy your rows from Excel, Google Sheets, or any spreadsheet app, paste them into the box below, and get properly formatted CSV back — ready to save or use in a script, database import, or analytics tool.
The tool is built for how people really work with spreadsheets. When you copy cells from Excel, they arrive as tab-separated text. This converter reads that structure and re-emits it as RFC-4180-style CSV: commas between columns, newlines between rows, and automatic quoting of any cell that contains a comma, a quote, or a line break. The result is clean, predictable data that won’t break your downstream pipeline.
This is invaluable for common tasks like migrating contact lists into CRM tools, preparing product catalogs for e-commerce imports, exporting survey results to analysis software, or building training data for machine learning models. Instead of fighting Excel’s save dialogs and locale quirks, you paste, convert, and copy — done.
Everything runs locally in your browser. No file ever leaves your machine, there is no size limit tied to a server, and the conversion is instant even for thousands of rows.

How do I copy cells out of Excel for this converter?
Select the cells you want (including headers), press Ctrl+C (or Cmd+C on Mac), then click into the input box and paste. Excel copies the selection as tab-separated text, which is exactly the format this converter expects. Pasting from Google Sheets works the same way.
Does it handle commas, quotes, or line breaks inside cells?
Yes. Any cell containing a comma, a double quote, or a line break is automatically wrapped in double quotes, and embedded quotes are doubled (""), following the standard CSV rules. This keeps the output valid even when your data contains tricky characters like "Smith, John" or multi-line notes.
Is my data uploaded anywhere?
No. The conversion runs entirely in your browser with JavaScript — nothing is sent to a server. This makes it safe for sensitive data like customer lists, financial figures, or any information you would rather keep off third-party services.
What if my paste uses commas instead of tabs as separators?
Copying from Excel and Google Sheets always produces tabs between columns, so the default path works out of the box. If you have data already separated by commas, use the JSON to CSV converter or a spreadsheet export instead — pasting comma-separated text into this tool would treat it as a single column.
